Abstract

The efficient activation of the O-O band in persulfate (PDS) with high energy was important and could be achieved by the interface engineering of catalysts. It was discovered that the robust bisphenol A (BPA) degradation could be achieved in the presence of PDS via different mechanisms with steel-wool-shaped Cu-Co3O4 composites obtained via in-situ hydrolysis of cobalt and copper nitrate with zeolitic imidazolate framework-67 after calcination. The calcination temperature at 483 K resulted in abundant oxygen vacancies in Cu-Co3O4 with the amorphous structure, which displayed about a 25-fold higher degradation rate constant (k = 0.385 min-1) than that (0.015 min-1) of Co3O4 for BPA disposal with PDS, possibly via forming the surface-activated complex process. The higher temperature (583 K) treated Cu-Co3O4 could also lead to the fast BPA degradation with the k of 0.670 min-1, which was more than 160-fold higher than the referenced Co3O4 and experienced the radical and nonradical processes, including the HO•, SO4•-, O2•-, and 1O2 as reactive oxygen species. The above difference was possibly due to the amount of oxygen vacancy, the ratio of metal ions with different oxidation states, and the interaction of Cu-O-Co in the composite.

钢-羊毛型Cu-Co3O4过硫酸盐可调降解双酚A界面工程

过硫酸盐（PDS）中O-O波段的高能量高效活化是重要的，可以通过催化剂的界面工程来实现。研究发现，在PDS存在下，用沸石咪唑酸框架-67原位水解钴和硝酸铜得到的钢-羊毛型Cu-Co3O4复合材料可通过不同的机制实现对双酚A （BPA）的稳定降解。在483 K的煅烧温度下，Cu-Co3O4具有丰富的氧空位，具有非晶结构，其降解速率常数（K = 0.385 min-1）比Co3O4的降解速率常数（0.015 min-1）高25倍，可能是通过形成表面活化的配合物过程处理BPA。高温（583 K）处理后的Cu-Co3O4也可以快速降解BPA， K为0.670 min-1，比参考Co3O4高160倍以上，并经历了自由基和非自由基过程，包括HO•、SO4•-、O2•-和1O2作为活性氧。上述差异可能与氧空位的数量、不同氧化态金属离子的比例以及复合材料中Cu-O-Co的相互作用有关。
